生物降解塑料的研究现状及问题

Development and Problem of Research of Biodegradable Plastics

生物降解塑料这一领域的研究和发展正成为人们普遍关注的焦点。生物降解塑料根据其降解机理和破坏形式,可分为完全生物降解塑料和生物崩坏性(致劣性)塑料两种。这种新型塑料涉及化工、高分子、生物学等多门学科,属于一项高新技术。尽管各国投入了较大的人力、物力,但至今还未普遍达到实用阶段,在研究开发、市场、应用等方面还存在许多问题。

The research and development of biodegradable plastics is becoming people' s focus. The biodegradable plastics can be arranged into complete biodegradable plastics and biomolder plastics by its mechanism and the shape of the demolition.Because this plastics involves chemical engineering 、 polymer and biology,it can not be used commonly now.There are many problem existing in the research、market and application of biodegradable plastics.
